METAL BARREL.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed January 211906. Serial No. 294.318.

T all whom it "may concern:

Be it known that I, EDWARD-G. COOK, a

citizen of the United States, residing at following is a specification accompanied by drawings, forming a part of the same, in which Figure 1 is a side view of my improved barrel. Fig. 2 is a central longitudinal section, and Figs. 3 and 4 are detail sectional views on an enlarged scale, showing the method of uniting the sections of the barrel to the rolling hoops.

Similar reference letters and figures refer to similar parts in the different views.

My invention relates to a metal barrel provided with projecting hoops, to facilitate the rolling of the barrel. Myimproved barrel is constructed of several portions, stamped, rolled or otherwise manufactured from sheet metal into the desiredshapes, and the rolling hoops are utilized to'fasten these separate parts together to form the completed barrel.

In the accompanying drawings l have shown abarrel formed in three parts, a central annular band 1 and two cup shaped pieces 2 and 3. The cup shaped pieces are alike, and like the annular band are made from sheet metal by stamping, rolling, or in any convenient manner. The sides of the cup shaped pieces 2, 3 are slightly contracted attheir closed ends to form shoulders 4, 5, over which the chime hoops 6, 7, provided with interior grooves S are. slipped. The con tracted sides are then expanded b pressure from the inside to fit the interior groove 8, thereby holding the chime hoops 6, 7, on the barrel.

On both sides of the annular band 1 and on the open ends of the cup shaped pieces 2,

3, I form flanges 1.0 which are fitted to engage the rolling hoops 11 of the barrel, as is hereinafter described.

' The rolling hoops, as shown in Fig. 3, are made of any convenient shape in cross section, and are provided with grooves 12 for the entrance of the flanges 10, and also with laterally extended flanges 13 which are turned down, after the flanges 10 are placed in the grooves 12, thereby securing said flanges 10 therein. This may be accomplished, as shown in Fig. 4, hya pair of rolls 14 to which pressure, is applied by any-conin the grooves 12 in the'rolling venient means, not shown, said rolls act in conjunction with each other and compress between them the flanges 13, but I-do not wish to limit myself to this method of confining the sections of the barrel to the-rolling hoops, as I am aware that other means may be employed for that purpose.

My improved barrel then consists of the two on p shaped ends 2, 3, made from sheet metal in any convenient manner, and one or more annular bands, also formed from sheet metal, with the various portions attached to intervening hoops, preferably by means of the flanges 10. These iianges 10 are fitted hoops 11, and the flanges 13 on the rolling hoops 11 are then turned down upon the flanges 10. The various pieces of the barrel are thus firmly secured together with water tight joint-shetween them, and the rolling hoops 11 are not only fastened on the barrel, but also serve to hold the sections of the barrel together.

. What I claim as my invention and desire to secure by Letters Patent is:

1. A metal barrel or similar vessel formed of annular sections having outwardly turned f langes at their edges, a. hoop connect-mg said sections provided with a recess in each side to I receive said outwardly turned flanges interior flanges on each side of the hoop below the recess projecting inside said annular sections and bendable flanges on said hoop bearing against the outer faces of said outwardly turned flanges of the barrel sections.

2. A metal barrel or similar vessel formed of annular sections having outwardly turned flangcs'at their edges and a hoop provided with a recess in each side, said recess being of a width. su'llicient to receive said outwardly turned flanges with the inside wall of said recess in contact with the inside of said annular section said hoop having a pair of bondable flangcs bearing against the outer face of said outwardly turned flanges of the barrel sections.

3. A metal barrel or similar vessel formed of annular sections having outwardly turned flanges at their edges, a hoop provided with a recess in each side, said recess being of a width sufficient to receive said outwardly turned flangeswith'the inside wall of said recess in contact with the inside of said an nular section, and means for holding said outwardly turned flanges in said recess.

' 4. A metal barrel or similar vessel formed of annular sm-iions haying-outwardly turned flanges :11;- thvir edges, a i'lOOPPIOVid ed with a recess in. each side to receive said flanges, with the inside of said annular section in conmm with one sidn of said recess, the periphery of said outwardly turned flange in contact with the other sidn 01' said recess and the face of said outwardly h'nnod flange in contact 1 l With the bottom of said recess and means for holding said outwardly turned flanges in the 10 I recesses of the hoop.
